Question

A boy runs towards a plane mirror with a velocity of 2m/s. with what velocity his image moves towards him

Answer 1

Answer:

Explanation:

the image also moves forward with the same velocity toward him for an observer outside but for the boy he will see the image velocity relative to his velocity since the velocity of boy and image are in opposite directions relative velocity = 2 - (-2)

  = 4 m/s . for the boy the image seems approaching him with 4 m/s velocity
